For above also no config changes still the clock doesn't changes

can you once again check my steps

1. My project dfu_lbs created . inside dfu_lbs created folder called child_image

2. in prj.conf added

      # Clock configuration
   CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

3..Inside child_image created mcuboot.conf and pasted 

  CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y
  CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_MAX_SKIP=0
  CONFIG_CLOCK_CONTROL_NRF_CALIBRATION_TEMP_DIFF=0

opened the project and cross verified with

project -> configure nrf connect sdk project

a. menuconfig

    

b. mcuboot_menuconfig

 

clock doesn't changed in mcuboot.

I am using SDK v1.4.2 does any thing need to change

This ncs version does not automatically load child_image configuration, so you need to add this just below the cmake_minimum_required() line in CMakeLists.txt:

list(APPEND mcuboot_OVERLAY_CONFIG
  "${CMAKE_CURRENT_SOURCE_DIR}/child_image/mcuboot.conf"
  )

 

Kind regards,

Håkon

Please add it just below the cmake_minimum_required() line.
